What is a farm trailer? What are the common types of farm trailers?

Trailer is a type of vehicle commonly used in the field of transportation, generally refers to its own no power device, the need to use a tractor to tow the vehicle, such as trailer RV, camper, is a kind of trailer. Agricultural trailers refer specifically to trailers used for agricultural mechanized production and transportation, such as common tractors.

Agricultural trailer is an important mode of mechanized transport in rural areas, which is of great significance to the improvement of production efficiency.

From the appearance and structure, the agricultural trailer can also be divided into full-mounted, mid-mounted shaft and semi-mounted:

1, full-mounted axle is usually placed at both ends of the trailer, can bear the average load of the carriage, even if not connected to the tractor, can also stand smoothly, the weight of the carriage is fully borne by the carriage itself, the tractor only needs to take it to run.

Full hanging

2. Middle axle type: The axle of the trailer is installed in the center of the car, so it cannot maintain balance independently when it is removed from the tractor. When connecting the tractor, the tractor needs to share a part of the weight of the carriage, but this proportion will not be too large, mainly by the center axle support.

Center axle type

3, semi-trailer: semi-trailer axle installed in the rear end of the car, so it can not independently maintain balance, tractor also needs to bear part of the weight of the car.

However, the difference between the semi-trailer and the semi-trailer is more obvious, the semi-trailer is the same as the fully hung and the middle axle, and it is connected with the traction hook of the tractor through the traction frame and the hanging ring. Semi-trailer is the front end of the carriage directly behind the tractor, through the traction seat and traction pin connection.

In general, no matter what kind of trailer, it is generally designed with a traction frame, hanging ring and steering device, so that it can maintain left and right swing or a certain degree of up and down swing during driving. This feature can improve the flexibility of the trailer, more suitable for the road conditions in the field, but also lead to the increase in the difficulty of reversing and the instability of driving, so the agricultural trailer is generally only used for field or short-distance transport, not for medium and long-distance transport.

With the improvement of the level of agricultural modernization, the types of agricultural trailers are becoming more and more abundant.

What kinds of common farm trailers are there? Different types of agricultural trailers are suitable for what field?

1, plate trailer

The pallet is the most common kind of agricultural trailer, and the top part of the carriage is the pallet structure, which is mainly suitable for the transportation of bulk goods, such as grain, sand, manure, etc., and is very widely used.

In addition to the common pallet trailer, there is a modified high pallet trailer, the height can be 1.2m, this model can transport grain, can also transport stored feed, and even can directly remove the baffle when necessary to use the flatbed car.

2. High hurdle trailer

From the appearance of the high hurdle trailer, it is like installing a high hurdle enclosure on the basis of the fence plate, this model is generally used for transporting stored feed, pulling grass and so on.

3, dump trailer

The dump function is widely used in the field of agriculture, such as some commonly used truck, high truck, flat car and other main transport function models, basically have the dump function.

Many of these models have also improved the self-unloading function, such as the addition of spring baffles, which can control the amount of goods dumped during unloading, and cooperate with the forward speed of the vehicle, and can also achieve tile-type unloading.

4, flat trailer

Flatbed trailer refers to the trailer whose bucket part is directly a flat plate, which is less used in the agricultural field and more used in airports, ports or industrial mines.

According to the different transportation needs, the flat trailer can be equipped with movable guardrails on all sides.

5, low flat plate trailer

The low flat plate trailer is similar to the flat plate type, except that it is significantly shorter in height from the ground. The height from the ground is small, the stability of transportation is improved, the goods are more convenient to get on and off the car, and the passing of vehicles on some high-limit sections is also stronger. Therefore, low flatbed trailers are generally used for transporting mechanical equipment, such as harvesters, excavators, etc. In order to facilitate the mechanical loading and unloading, some models are also specially equipped with hydraulic ladders.

6, skeleton trailer

The skeleton trailer is similar to the low flat trailer in appearance, except that the body is composed of longitudinal beams, beams and front and rear end beams welded frame, and the chassis structure can be seen directly from the body above. The skeleton trailer can be modified for the transport of machinery and equipment in the agricultural field.

7, liquid fertilizer sprinkling car

It can also be called a tank trailer, which is generally equipped with spray ports on both sides or the rear side of the cargo tank, mainly for liquid fertilizer sprinkling.

8, solid fertilizer sprinkling car

It is mainly used for throwing solid fertilizer, which is equipped with a high fence board around the top, and a sprinkling device is set behind it, which can achieve uniform sprinkling along with the progress of the vehicle.

Some solid-state fertilizer spenders can be converted from rail-board trailers, which can be used for both transportation and manure spenders, and the vehicle application rate has been improved.

9. Straw/grass pickup truck

This pickup truck is mainly used for picking up and collecting scattered grass or straw.

10. Bale pickup truck

As the name suggests, it is used for bale picking and loading, and can also be used for bale straw picking.

By the way, this straw bale pickup truck is generally used in conjunction with straw baling trucks, one baling, one loading, the efficiency can be greatly improved.

11. Mobile power station

There are many styles of mobile power stations, such as hand-pushed, three-wheeled, four-wheeled, car-type, trailer type, etc., and trailer type is generally four-wheeled full-mounted, mainly used for power supply for field work.

12, multi-purpose trailer

In addition to the above common types of trailers, there are also some main multi-functional agricultural trailers on the market, such as trailers that can transport grain, pull harvesters, and pull excavators, etc. These models have different functions, basically covering two to three functions, mainly in order to improve vehicle utilization and attract more consumers.

Under normal circumstances, the common tonnage of agricultural trailers is mostly concentrated between 3t-10t, of which 5t and 8t are the most common.

Different from the common freight trailer in the logistics and transportation industry, agricultural trailers are generally used in agricultural production, and different agricultural activities often require different trailers to assist. Therefore, the types of agricultural trailers are relatively richer and the functions are more diverse, resulting in a variety of differences in their appearance, tonnage, wheel base and other parameters, which to a certain extent led to the niche of its parts.

Take the trailer axle, for example. Want to buy a 13t drum brake bridge is relatively simple, all can do trailer axle manufacturers almost have this product, because this is a very popular trailer axle market, the parameters are basically very different, many manufacturers can even provide spot. However, if you want to buy a 3t low flat trailer axle, but also the wheel base and other parameters fully match, I am afraid it is not so simple, unless specially customized.

The independent production capacity is the most basic, product design and quality assurance capabilities are essential, only in this way can we produce trailer axles that meet customer needs, perfectly match customer vehicles, and have reliable quality and long service life.
